Module Name

MRIBiasFieldCorrection

MRIBiasFieldCorrection corrects for the intensity inhomogeneity in 3D MRI images. Left image: input image with intensity inhomogeneity from lower corner to higher corner. Right image: output image where the intensity inhomogeneity has been corrected.

Module Description

MRIBiasFieldCorrection corrects for the intensity inhomogeneity due to MRI gain field distortion.
It first estimates the bias field and then 'subtract' it from the image.
This module implements the so called methods 'N3' and 'N4' (see references at the bottom of this page).

Usage

Step 1/24. To open the input image, click on 'File' and then 'Add Volume':
